Method and apparatus for processing display color signal

Image Number 3 for United States Patent #5142272.

A color video signal processing method and apparatus wherein the compressed display data of each pixel consists of a color identification code and a color saturation data relative to the color or luminance of the pixel having the maximum saturation change in comparison with an adjacent pixel, and where the original color data is reproduced from such display data. Furthermore, a plurality of representative colors are prepared per value of specific color, and the optimal color is selected per pixel to provide the display data. A distribution of color appearance frequencies is employed for determining the representative colors, and such colors are so selected as to have the maximum spectral distances from one another.
